Abstract: | Most current models of spindle assembly checkpoint signaling involve inhibition of the Cdc20-APC by Mad2 protein. Interestingly, a paper from Hongtao Yu and colleagues in this issue of Developmental Cell suggests that the Cdc20/APC can also be inhibited in a Mad2-independent manner by a complex of proteins that includes BubR1. |
